EAST BRUNSWICK — After his car struck a motorcycle and its driver in South Brunswick, throwing the cyclist into the street, the intoxicated motorist drove away, dragging the motorcycle with sparks flying for two miles, police said.

East Brunswick police stopped the driver, identified as Chandresh Chitalia, 47, of East Brunswick, after officers saw sparks flying out from under his Nissan Altima, authorities said.

The accident occurred at 8:25 p.m. Thursday on Cranbury Road at Davidson Mill Road in South Brunswick, when Chitalia’s car struck the motorcycle stopped at a traffic light. The cyclist, Christopher Kobi, 39, of South River, was knocked onto the road, said South Brunswick police Detective Sgt. James Ryan.

Witnesses told police Chitalia got out of his car, attempted to pull the 2008 Harley-Davidson motorcycle free from his vehicle, but failing that, drove north on Cranbury Road, Ryan said.

Officers found Kobi lying in the road and semiconscious. He was taken to Robert Wood Johnson University Hospital in New Brunswick for treatment of non-life threatening injuries, Ryan said.

He said Chitalia had a strong odor of alcohol and trouble standing, and told officers he heard a thud, but was unaware he hit anything.

Chitalia was charged with driving under the influence, assault by auto, leaving the scene of an accident and failing to aid an injured person. He was being held today on $75,000 bail at the Middlesex County jail in North Brunswick.
